Hi Ted,

I have mentioned on git that:
1. The reference to RFC 8843bis is missing

2. The following language is factually incorrect:

This is by design, but could cause issues in the rare case of sending a
subsequent offer as an initial offer to a non-bundle-aware endpoint via
Third Party Call Control (3PCC).

Primarily, this will cause issues if a subsequent offer is used as an
initial even with bundle-aware end points. An offer with no bundle-only
attributes for bundled m= lines might not get processed correctly. Second,
I would not comment on how frequent this call scenario is going to be
unless we have to.

My suggested language was:

This is by design, but could cause issues in case of sending a subsequent
offer as an initial offer due to Third Party Call Control (3PCC). In such
cases, the signaling application is responsible for adding bundle-only
attributes to the offer so that it can be used as an initial offer.

Best Regards,
_____________
